Improve Wayland protocol version selection.

Improve Wayland protocol version selection.

VK-GL-CTS issue: 2252

Requesting specifically version 3 of the protocol makes the
wl_surface_damage_buffer() API unavailable to the client, even if
the compositor supports it. This may effectively disable
the EGL_EXT_swap_buffers_with_damage extension in the EGL implementation.

The wl_compositor protocol version 4 was released in Wayland 1.10
in february 2016. It contains a new define:

#define WL_SURFACE_DAMAGE_BUFFER_SINCE_VERSION 4

and a new API:

wl_surface_damage_buffer(struct wl_surface *wl_surface,
    int32_t x, int32_t y, int32_t width, int32_t height);

Requesting "at least version 3" is still backwards compatible with older
compositors, but doesn't block the newer ones from providing version 4
with the wl_surface_damage_buffer() API. This API can be used by EGL
to implement the EGL_EXT_swap_buffers_with_damage extension.

Affects:
    dEQP-EGL.functional.swap_buffers_with_damage.*
